First one n=4
Second one h=11
Third one y=11.2
Fourth one 5x 2x + 5 x 4
Step-by-step explanation:
First one you add fifteen to both sides and then divide by 14.23
Ответ:
5) n = 4
6) h = 11
7) y = 11.2
8) 5 • 2x + 5 • 4
Step-by-step explanation:
5) 14.23n • 100 - 15 • 100 = 41.92 • 100
1423n - 1500 = 4192
1423n - 1500 + 1500 = 4192 + 1500
1423n = 5692
1423n / 1423 = 5692 / 1423
n = 4
6) 12h - 33 + 33 = 99 + 33
12h = 132
12h / 12 = 132 / 12
h = 11
7) 4(y-5) / 4 = 24.8 / 4
y - 5 = 6.2
y - 5 + 5 = 6.2 + 5
y = 11.2
8) 5 • 2x + 5 • 4
